Known Issues

The known issues are grouped as follows.

vCenter Server, vSphere Web Client, and vSphere Client Issues
  • Trying to disable the usage of Hyperthreading after enabling the HyperthreadingMitigation option on an ESXi host might trigger an incorrect message in the Processors view

    When you enable the HyperthreadingMitigation option on an ESXi host, by setting VMkernel.Boot.HyperthreadingMitigation to True, the usage of Hyperthreading by this ESXi patch is disabled, regardless of the previous settings. If you decide to change the setting VMkernel.Boot.Hyperthreading to False to disable the option, you might see the message Disabled(Enabled on restart) in the Processors view. In fact, Hyperthreading is not used after the restart.

    Workaround: None. Ignore the message.

  • After patching to vCenter Server 6.0 Update 3h and ESXi600-201808001, the vSphere Client displays a generic message for configuration issues in the Summary tab

    After upgrading your system to vCenter Server 6.0 Update 3h and ESXi600-201808001, you might see a generic message Configuration Issues in the Summary tab of the vSphere Client.

    Workaround: Log in to the vSphere Web Client to see the full message This host is potentially vulnerable to issues described in CVE-2018-3646, please refer to KB55636 for details and VMware recommendations.

Installation, Upgrade and Migration Issues
